The Dallas Cowboys have restructured three contracts this week. Now they're turning to defensive end DeMarcus Ware to help them get under the salary cap.

The team approached Ware's representatives Tuesday about redoing the veteran pass rusher's contract, a person with knowledge of the situation told USA TODAY Sports on condition of anonymity because negotiations were to remain private.

Ware, 31, is due $12.75 million in salary and bonuses in 2014 with a cap number of more than $16 million — too much for the Cowboys, who entered the week well above their adjusted cap of $134.28 million.

They cleared $8.5 million with so-called "simple" restructures of the contracts of linebacker Sean Lee and safety Orlando Scandrick, converting portions of their base salaries to signing bonuses. They announced Tuesday they've done the same with quarterback Tony Romo's contract, clearing another $10 million.

Ware signed a six-year contract extension in October 2009 that has been renegotiated three times already, clearing cap space for the Cowboys each of the past three offseasons. This time, he likely is headed for a pay cut if he wants to stick around.

In 13 games last season, Ware had six sacks, the lowest total of his nine-year career.

The deadline for coming into compliance with the 2014 cap is 4 p.m. ET on March 11.
